The present paper presents a fully differential 60 GHz four stages low-noise amplifier for wireless applications. The amplifier has been optimized for low-noise, high-gain, and low-power consumption, and implemented in a 90 nm low-power CMOS technology. Matching and common-mode rejection networks have been realized using shielded coplanar transmission lines. The amplifier achieves a peak small-signal gain of 21.3 dB and an average noise figure of 5.4 dB along with power consumption of 30 mW and occupying only 0.38 mm2pads included. The detailed design procedure and the achieved measurement results are presented in this work.

Abstract The wireless telecommunication systems have an undeniable role in today's society. The rapid progress of wireless services and applications accelerates demands for high data-rate reliable systems. The 60 GHz band with its 5 GHz globally unlicensed available spectrum, provides a great opportunity for the next generation of high data-rate wireless communication. Despite this attractive bandwidth surrounding 60 GHz, there are still many challenges to be addressed such as the loss performance and the integration with other systems. Low Temperature Cofired Ceramic (LTCC) technology, with its unique and mature multilayer fabrication process, has excellent capability of realizing miniaturized 3D low loss structures to overcome these challenges. Since, one of the key components in any communication system for both interconnecting and designing components is Low loss transmission lines, in this article we overview the performances and challenges for four different most practical transmission lines at 60 GHz in LTCC: Microstrip, Stripline, Coplanar Waveguide (CPW), and LTCC Integrated Waveguide (LIW).

Measurement Results

In this paper, a multi-layer LCP substrate fabrication process was described and millimeter wave transmission lines and filters were designed and fabricated on the LCP substrate. Various transitions from a CPW to a microstrip line with their characteristic impedance being 50 ohms were investigated. The characteristics of the wirebonding assembly for connecting two transmission lines was also examined. The measurement results show that an insertion loss of 1.3 dB at 60 GHz can be achieved for the two-wire bonding trasmisssion line including two transitions from a CPW to a microstrip line.
